My interactions with cops have been okay I'd say.

I was driving home late one night from work in the countryside and a cop pulled me over. He thought I was drunk driving... I wasn't, I was just tired from work! He told me to be careful and offered to follow me home to make sure I didn't die. I said "sure". Whatever, it wasn't a big deal.

Another time it was raining and I was in a new car for me and I tried to brake but I accidentally hit a lady's car on her back bumper. The lady was a mega bitch about it even though there was no damage to either car. She called the cops and a cop came, but the cop basically told her that she had wasted everyone's time. xD He didn't give me a ticket, just told me I got lucky and to try to be more careful next time.
